Marine tuning is our specialty
Marine engines have different requirements than automotive engines.
Load characteristics, operating conditions, cooling, propeller load and other marine specific factors all need to be considered when developing a professional tuning solution. An engine that spends its life at sustained high load with variable fuel quality require carefully adjusted calibration to ensure your client can enjoy his tune for years to come.
With extensive experience in marine ECU tuning, our focus is on developing software specifically for marine applications.
Marine ECU tuning is what we do.

- Load characteristics under sustained marine duty
- Operating conditions and cooling behaviour
